Here's an update from Doug that he posted on the Science Madness forum: He moved into a new house and is currently busy with that. He is working on settling in, finding time to do chemistry, and setting up a new lab. He probably won't be back soon, but when he is, expect a new lab setup!

[@hongbitter7142]

More videos Doug! We need more

[@spinjector]

Hi Doug. I'm a fan of your videos and watch them regularly. I have some suggestions to improve the sound quality of your audio. I'm not sure what you record with, if it's a video camera or cell phone. If it's a cell phone, the solution is easier, see if you can use a bluetooth headset with noise cancellation. First, it will get the microphone closer to your mouth so the sound of your voice is louder in comparison with the noise in the background. If you're using a video camera with a microphone input, get one of those over the ear microphones like you see rock stars using and plug it into the microphone input. Either solution should be able to be had for an economical price. Ebay and Amazon are overflowing with bluetooth microphones, and the over-ear performance microphones can be had at any music store. Whichever one it is, be sure to look for the terms noise-cancelling, directional, or if it's a performance microphone, look for the term cardioid pattern. Barring technological improvements, there are three main sources of noise in your videos: the aspirator, the vent fan, and OMG THAT SQUEAKY LAB JACK lol. Please, for the love of everything and anything to do with my eardrums, please put some grease on that lab jack lol. If you're concerned about volatile hydrocarbons that may interact with any of your experiments, I understand, but perhaps you could just use a dab of that heavily fluorinated grease that you use to grease your glass joints. Should be no reaction problems there, eh? The vent fan would require a little more engineering, and might be more difficult to replace. But with fans, slower and bigger is quieter. Perhaps one of those big white plastic house fans that people get for the summertime? Also with a larger fan, the frequency of the noise it generates would be lower, and less likely to pierce through to the microphone and the recording. And lastly, the remaining screaming roar in your videos is the aspirator. The solution to there is simple, just get a piece of hose about 12 to 18 in long and jam it on the outlet. Make it just long enough so that you can lay the end down in the sink, or put it right down in the drain. Or possibly just in a container sitting on the bottom of the sink to catch the water, after which it can gently overflow and then go down the drain. Peace out bro, keep up the good work.

[@hubrisnaut]

Definitely too much H2SO4. I copied your prep this week also running it on the 1 m scale but reducing the sulfuric acid to 25ml. No issues drying it on the pump and it proceeded at essentially the same speed. Followed up with a re-xtal in hot MeOH to clean off lingering sulfuric.

[@mistertheguy3073]

Hey, I love chemistry too!

[@RushilFernandes]

Thanks for posting. It's always fun to watch organic synthesis videos. I would like to ask, however, why you don't use TLC to monitor the progress of your reactions. It would make things so much easier IMHO. I spent my PhD constantly doing column chromatography and TLC and for some reason I haven't seen a single KZbin chemistry person do either.

[@RobsMiscellania]

I was similarly dissatisfied with the lack of chromatography on KZbin as well, so I decided to equip myself and I will shortly be producing videos for my channel. I will be presenting organic synthesis with applications to medicinal chemistry and will be prominently featuring the use of TLC and column/flash chromatography. Since I plan on making series of videos of multistep syntheses, it will sometimes be required for me to purify a compound I have synthesized in order for the next step of the synthesis to take place successfully. I will also be using melting point, refractive index, and colorimetry where applicable in order to more fully characterize these sets of compounds. I hope you'll join me for some exciting chemistry! I plan to begin with an example of the Sandmeyer reaction shortly after the beginning of the new year.

[@DougsLab]

I want to see what you come up with!

[@mwilson14]

Good deal and I'll be making videos again soon which will be better quality than my previous number of low quality posts. I have a fair amount of ferrous oxalate and even more potassium ferrioxalate, the latter of which I need to use soon since K3Fe(C2O4)3 is very light sensitive and will decompose and become useless. I was thinking about making calcium oxalate to simulate kidney stones. LOL. I have a microscope with a mounted camera that I'd like to upgrade so I can take non-choppy video and make that into a theme for my channel. I don't see tons of people doing micrograph photo/video stuff and I'd like to see others doing a lot more of that. I usually use my camera on my phone out of convenience of not having to hook the microscope up to my laptop, plus I can get a better picture since my phone has a higher resolution. I updated my google header photo with phosphate stabilizers I isolated from a Pepto Bismal bismuth extraction and lit it with UV light under my microscope. It's a pretty cool photo if you want to check it out.

[@mwilson14]

I just found out something that made me jump up with excitement as I've been working on crystallizing neodymium sulfate for a couple of months! I have a small bit of crystals but haven't grown since they formed weeks ago. They are a beautiful lavender color. Most everything else I have created so far is clear, white, yellow, green, blue and dirty orange in color. I do have my nearly black copper acetate crystals, which I've been very fond of, but nothing yet beats the neodymium sulfate crystals. There is a topic I found on the Sciencemadness forums and it involves extracting the Nd from solution by precipitating it out via an oxalate. I've not found too much info on Nd, but I guess I wasn't searching incredibly hard either. I didn't realize that Nd is less soluble in near boiling water than it is in cold!

[@mwilson14]

I posted a short video on my channel of the results from my neodymium extraction experiment using oxalic acid. I'll be making a how-to video on the subject in the future. kzbin.info/www/bejne/roDGXnuordeVnJo
